A lens works by the difference in refractive index between the material in the lens and the surrounding medium. So a lens put in a medium that has exactly the same refractive index would not be a lens, it wouldn't bend light at all.
A convex lens acts as concave lens when it is kept in a medium whose optical density is higher than the lens itself. And the vice-verse is also true .i.e, a concave lens can act as convex lens too .
They are both made of a transparent medium with a refractive index > 1.Both have one or two sides possessing a curvature which, combined with their refractive properties, causes light rays to be deflected(convex ()> ) or (concave )(< )
The answer depends on the medium which it then travels through.
No pure mirror refracts. Refraction is caused by a change of the medium through which the light passes, which is accompanied by change of refractive index (change in the velocity of the light).
Usually a convex lens made up a material with higher refractive index would act as a converging device when kept in a medium having lower refractive index such as air. But when it is kept in a liquid as said with higher refractive index then convex lens would become as a concave lens. Now it would diverge the rays entering through it right from the liquid with higher refractive index.
an electrolyte is any substance containing free ions that behaves as an electrically conductive medium.
baking soda is an acidAnswer 2No, it's not. It's an alkali (base)Actual fact...Baking soda is a solid salt in aqueous medium it behaves as a weak base but it is actually Amphoteric , it means in acidic medium it behaves as a base and in basic medium it behaves as an acidBaking Soda Is A BaseAlso baking soda has a pH value of 9 which makes it a base.Baking soda, or NaHCO3, is a weak base, so it is alkaline.

The Sun is classified as a medium to medium-small yellow star. As stars in our galaxy go, the Sun is, truthfully, about as ordinary as stars get - but it does the job!

biologist used aqueous solution to perform chemical test as this solution behaves as the medium for chemical reaction and is also the medium of chemical reaction in living beings so that is why biologist use aqueous solution.
Here are several: moderate, medium, limited, calm, quiet, steady, ordinary, subdued, repressed and near.
No pure mirror refracts. Refraction is caused by a change of the medium through which the light passes, which is accompanied by change of refractive index (change in the velocity of the light).
IF you meant a convex lens - light entering the lens is bent because it's passing from one medium to another - to converge at the focal point.
they were medium in height and had parrot feathers in their hair and Married woman wore cotton around their waist ordinary people did not.
